Abstract

The application belongs to the technical field of gas separation, and particularly relates to a polyvinylamine gas separation membrane and a preparation method and application thereof. The polyvinylamine gas separation membrane provided by the application comprises polyvinylamine and silver nanowires loaded with MOFs. The silver nanowires loaded with MOFs are introduced into the gas separation membrane, the silver nanowires can effectively regulate the arrangement of polyvinylamine segments, and the formation of crystalline regions is avoided, and the MOFs can provide additional CO2 adsorption sites, and further improve the separation performance of the gas separation membrane for CO2.
